I read the site and look at the picture in the site.It's talk about the heart and the circulation system.I like the website because I like to learned a few of people's body.It can let me study better.After I raed the site I learned:the heartbeat is because the heart is cleaning our blood.There are two color of blood.One is blue and the other is red.The blue blood are the dirty blood they need to clean.Than the red blood is the clean blood.The heart has cleaned,so it is the circulation system of the heart.
